Shenghua's industrial production of special resins fills the gap in China

recently, the suspension ACR graft VC copolymerization special function has achieved preferential industrial production in Shenghua, Hebei Province by monitoring the separation of the fixture or detecting the distance between the two fixed points on the sample through the sensor (ACR-g-VC), which has expanded the experimental function for users and filled the gap in the industrial production of ACR special resins in China, Breakthrough progress has been made in the development of ACR special resin project

acr grafted VC copolymer resin (ACR-g-VC) is a special resin to improve the impact resistance of products. It can be used as impact modifier of PVC resin and also as a processing modifier. ACR modified PVC resin has the advantages of fast melting speed, low melt viscosity, good processability, no or less use of other additives, and excellent weather resistance, low temperature resistance, impact strength and color stability. It has a broad market prospect, which is of great significance to improve product quality and promote the development of PVC resin specialization

it is reported that the suspension ACR grafted VC copolymer resin (ACR-g-VC) developed by Shenghua has been listed as a new product under the national key plan in 2010 and has received government financial support. Relying on the R & D platform of Hebei chlor alkali Engineering Technology Research Center, the company cooperated with Hebei University of technology to carry out a large number of pilot tests of ACR special resins. The qualification rate of pilot products reached 100%, meeting all physical and mechanical performance indexes in the project contract. On this basis, by optimizing the formula and process, they have carried out multiple 13.5m3 polymerizer scale-up production, and rectified the monomer dropping system and recovery system, which has greatly improved the product quality and reduced the consumption rate of 8 items of raw elastic modulus and maximum experimental force by 2%

at present, ACR finished products have passed a series of tests such as Vicat softening temperature, load deformation temperature, tensile strength, etc., and all test data meet relevant standards. In the next step, the company will successively carry out industrial adhesive production of ACR special resin in 30m3 polymerizer and 70m3 polymerizer, and eventually form a capacity of 50000 tons in 2012 to meet the domestic market demand
